The short answer is, it depends.
There are people that say they can handle 500mg of test with no AI and don’t get high estro problems and symptoms. Others go on TRT at 100mg and their nips combust. That’s quite a bit of variance. Personally, my E2 can be high normal or even a bit over and I get no high E2 symptoms and I feel great. Others feel best at the low end. If I were you I would get bloodwork when you feel the best with the least side effects and work around that.
